About One Fact Inc
one fact in one place, One Fact everywhere
One Fact offers professional services, consulting, training and support around systems modeling, embedded control and for the BridgePoint xtUML modeling tool.
We specialize in eXecutable Translatable UML (xtUML). We help customers improve their application development process by leveraging the benefits open-source xtUML provides. This means your product has a faster time to market, is more robust, and has reusable components for future projects.
Our expertise spans all three areas of xtUML: application modeling, model execution, and translation to implementation code.
Of course, since our team built BridgePoint upon the Eclipse framework, we have extensive experience using Java to create and enhance application software. We also have many years of experience in embedded programming covering a variety of industries and applications.
Additionally we offer consulting around UML standards, modeling techniques, model review, Eclipse, Java, C/C++, embedded software, legacy applications, configuration management, issue tracking, engineering processes, tools integration, model-driven workflows and more.
We can customize and extend the open-source xtUML tools to meet your needs.

Self-Driving cars seemed to be so far in the future. However, we already have cars that can parallel park, avoid obstacles and even change lanes on the freeway. With accelerometers, GPS and LiDAR, a control system can assist you in making a safe lane change.

The richest source of information about xtUML is found on xtuml.org. Specifically, there is a ‘Learn’ menu item with all kinds of resources. Books: xtuml.org/learn/books/ For a high-level overview, I recommend MDA Distilled. For deeper Executable UML, I recommend Mellor/Balcer and then Rastrick. Articles: xtuml.org/learn/articles/ Training Course: An interactive online training course is available that

Look for One Fact at various conferences, on campuses and in cities near you. Lafayette, Purdue, Austin, UK and Japan are planned. Discuss Shlaer-Mellor development and xtUML… and maybe pick up some cool 1F swag!
A referential attribute (aka foreign key) is an attribute that refers to another attribute which is an identifier (aka key) in another class. Shlaer-Mellor supports the concept of combining two referential attributes that must always have the same value. This is a powerful way to constrain the data set represented in your model. This concept can

This paper was written and presented at an IEEE conference in Niigata, Japan. It continues to garner interest from high school and college teachers. Teaching UML Modeling Before Programming at the High School Level
API and MC-Java The API to the xtUML metamodel is simply the xtUML metamodel viewed as an xtUML model. Applications that wish to interface are written in xtUML and operate on the metamodel as they would any other xtUML application model. Almost nobody access the xtUML metamodel with native hand-craft Java. Of course this is

Hey Professor, In this email I’m going to give you some background information on xtUML, the link to what we call an “analysis note” (the first stage of our engineering process), and my proposal for a delivery schedule. The analysis note you will read does not make much sense unless you are familiar with xtUML
